  1. 215. Hadron Structure from Lattice QCD
    Dr Jeremy Green (Institut für Kernphysik, Johannes Gutenberg-Universität Mainz)
    08/09/2014, 14:00
    Section B: Light Quarks
    Recent progress in lattice QCD calculations of hadron structure will be presented, with an emphasis on nucleon structure. Calculations of nucleon form factors have long been difficult to reconcile with experiment, but with advances in both methodology and computing resources, this situation is changing. Agreement with experiment is beginning to be obtained for several key observables, and...

  2. 61. Leading chiral logarithms for the nucleon mass
    Dr Alexey Vladimirov (Lund University)
    08/09/2014, 14:30
    Section B: Light Quarks
    We present the method of calculation of leading logarithms for the nucleon sector of chiral perturbation theory in heavy baryon formulation and in the relativistic invariant formulation. We have studied the leading logarithm behavior of the nucleon mass up and present the expression for it up to four-loop order exactly. We also present some results up to six-loop order as well as all-order...

  3. 183. Overview and status of the proton radius measurements
    Miha Mihovilovic (Johannes Gutenberg-Universitaet Mainz)
    08/09/2014, 14:50
    Section B: Light Quarks
    The discrepancy between the proton charge radius extracted from the muonic hydrogen Lamb shift measurement and the best present value obtained from the elastic scattering experiments, remains unexplained and represents a burning problem of today's nuclear physics. After more than 50 years of research the radius of a basic constituent of matter is still not understood. This...

  4. 14. The hadronic corrections to muonic hydrogen Lamb shift from ChPT and the proton radius
    Clara Peset (Universitat Autonoma de Barcelona /IFAE)
    08/09/2014, 15:20
    Section B: Light Quarks
    We obtain a model independent expression for the muonic hydrogen Lamb shift. The leading hadronic effects are controlled by the chiral theory, which allows for their model independent determination. We give their complete expression including the pion and Delta particles. Out of this analysis and the experimental measurement of the muonic hydrogen Lamb shift we determine the electromagnetic...

  5. 257. Non-ordinary meson couplings in the 1/Nc expansion
    Jose R. Pelaez (Universidad COmplutense)
    08/09/2014, 15:40
    Section B: Light Quarks
    We study the large Nc behavior of couplings among light meson states with different compositions in terms of quarks and gluons. We shortly review the most common compositions of mesons, which are of interest for the understanding of low-lying meson resonances, namely, the ordinary quark-antiquark states as well as the non-ordinary, glueball, tetraquark, etc. We dedicate special attention...
